Update:
He was spotted to the west of Dick Bell Park/Sailing Club at approx 5:30 tonight. We were in Bells Corners at the time and got there about 5:45. We were not able to locate him although we cruised through streets and back yards for 2 1/2 hours. At 8 or so I got a call from someone waiting for a bus at Nortel who spotted at him and tracked him till he hit the woods just west of the parking lots. We were just down the street at the time and got there 2 minutes later but couldn't catch up to him again. A couple, who was walking a dog which Tucker would normally go investigate, saw him and said he looked terrified. They tried to bribe him with a treat but no go. We're taking tomorrow off and are going to try and locate him in the same area again.
